Wiring Up 1 DVC Sub , to 2 channels of an amp.

[loveeemachine 1]

Sorry about this really really , noobish question but i was doing research and couldn't find this answer out myself.

Materials :

AMP-

http://www.shopping.com/xPO-Pyramid-PB448 (worst amp in life, but its all i have laying around , until my other one ships in mail.

SUB -

Fi SSD 15 DVC 2 ohm.

Is it possible to wire up the left REAR channel of the amp to one voice coil and the other voice coil to the right REAR channel of the amp to get the 250rms per channel @ 4 ohm. to equal 500rms.

or

since the amp is brigdable , wire both voice coils together and bridge them into one channel?

(AMP is not 1 ohm stable , so i'd need to wire them for 4 ohm.)

Thanks i just wanted to ask before i blow up my , speaker/ amp. XD

This info. would really really help,

If your getting a SSD 15, you don't wanna cheap out and get that pyramid amp. You need an mono class d amp that is 1 ohm stable for that sub since it is 2ohm DVC.

Sundown saz2000d

you could run one coil to each channel if you wanted to, but that sub is going to be very underpowered.

the pyramid would be underpowering the sub. not the sundown. my bad

Yea i kno

Kills me but i'm waiting on my new amp to come in the mail.

I'd kill for the money to buy a Sundown saz2000d

settling with a hifonics 1200 @ 1 ohm.

so it should run easy to push out 800 ish watts, an would match up nicely with the SSD correct?

That would be quite a waste of power, the RMS of the SSD is only 800.

You can either wire one voice coil to each channel or wire the coils in series and bridge those two channels of the amp. You'll get the same power either way.

He states he already has the Pyramid amp lying around so $$ wasn't spent this time around for that amp.

To the original Q, yes you can do it, but do yourself a favor and get a 0 dB test tone at ~60Hz and set a DMM to VAC and take a reading on the amp at the amps speaker terminals and see what the voltage is per ch. Sense the rear 2 chs on that amp share the same gain pot, if the reading is more then .5 VAC between the two chs then DO NOT run it this way.

Thanks everyone for the responses.

(I hooked it up only the sub , with a 12v battery and ran the RCA from the 360 to the amp)

BUT i wired it up numerous different ways and couldn't get none to work, i heard the music faintly playing in the woofer, but the beat would NEVER drop.

I cone didn't move, at all i could hear little things around my house shaking so it was doing something. . .

But i didn't get anything excursion AT ALL, i just assumed this is because that amp just sucks bee'z wax and couldn't even move the dam cone of the sub..???

Five minutes before i hooked up a better amp (friends) and had it bumpin to that amps potential it brought it into protect mode everytime gain went up . (only a 270rms @ 4 ohms , not 1 ohm stable)

So its obvious not the subs fault, is it possible to have an amp that is just not strong enough to make a sub move?

I'm sure i wired it properly, i tired so way different ways thinking WTF. all same results.

Is my conclusion that this amp just doesn't have what it takes. .

I hooked that same pyramid amp up the earlier day to a lil memphis 12, and it had it movin around a little.

That amp isn't stable at 2ohms in stereo either. If the specs say it is, they lie.

You need to wire it to 4 ohms bridged.

Heres how i wired it.

(NOne for more than 45 seconds, b/c they didn't work)

Both Voice Coils bridged into 1 channel. ( front and rear)

2 Channels bridged into 1 voice coil

1 Channel per voice coil. ( running both channels at once, Rear right , rear left)

Wired it in Series. (+ and - to one channel of amp, then + and - together linked on the other voice coil)

None of them moved the cone, there were vibrations coming out but no movement that could be caught by the eye.

i switched the amp from mono to stero, just made the voices clear.

Gain was turned up, freq. up.

Am i missing something?

Were you using the highpass filter instead of the lowpass

No, i don't think that amp even has a highpass. lol

I was using the frequency response.

[KU40 173]

That amp does have a crossover, and the frequency control knob is the crossover point. Just make sure the switch is "on", and set it for about 80 hz. Other than that, that amp is rated at 65 x 4 @ 4 ohms, so really it may do 40x4, so the sub is probably only getting 80 watts. It won't move a ton.

Your most easy wiring configuration is probably with the coils in series and then bridge the rear channels.
